Title: Control circuit for screen wiper drive for vehicle - allows pause duration to programmed by driver with interval operation and digital storage for control
Inventor: WASKIEWICZ LUDWIK
IPC: B60S1/08
Filed: 1992-03-12
Abstract: A transmitter, e.g. a selector switch with an adjusting lever, locking in different positions, is provided, for producing at least three different electrical transmitter signals which, if they represent a duration signal, establish at least three different operating modes for continuous operation: namely, whether the wiper remains continuously switched OFF, or works continuously in interval operating mode, or works continuously without pause. One of the producible transmitter signals serves as a cotnrol signal, which alters the pause duration in interval operating mode. The control signal is produced by moving the transmitter from the interval operating position in another position and back into the interval operating position so that the duration of the setting outside the interval operating position corresponds to the duration of the control signal. The transmitter is connected to a control circuit which measures the duration of the control signal and prevents the storage of a new pause value if the duration of the control signal is shorter than a power threshold value. ADVANTAGE - Interference to wiper operation causing readjustment by driving leading to irritation is at least practically eliminated.
